Bart, sorry about your bad experience with your Silverado and good luck with your new Ford p/u, just remember Ford doesn't want you to haul gravel in the bed, it's delicate after all. 

No new Ford here. All four of mine are 7, 21, 21, and 55 years old respectfully. This 2017 Chevy will be garaged right beside it’s 1977 Chevy Grandfather. Once the 2017’s defective driveline components are replaced it will be subjected to no less than 15 years of service, if not 40 years of service like my 77 which only has 57,000 miles on it. C20 Scottsdale with 454 engine and 400 turbo trans. Everything still works like new!

It would be nice to know how this was handled.

Warranty?

No son, you screwed the pooch now pick up the check.

 

Warranty repairs underway!

Regardless your screwed... The on board computes now loop count and gm know how many times it's been programmed .

When it comes back even one count higher then their records they will deny the warranty on the truck for good.

They even know if a code reset has been done but I haven't seen them do anything about that yet.

 

 

Warranty repairs are underway. It will take about a week.

Good news!!  Does dealer know you tuned the ECU at one time?  I'd be concerned about discussing all this on a public forum especially with your name and location disclosed.  

 

Hope the repairs give you a better than new truck.

A 98mph limiter is standard on many GM trucks/SUVs, has been for years, long before the K2s.  When you mentioned the actions of the torque converter, that was your first clue that something was wrong.  From reading posts on these boards it seems GM is having some long teething troubles with torque converters on the K2 for some reason.

 

Not a fan of aluminum drive shafts, they twist apart too easily.  But that could be precisely why GM is using them, to prevent damage to other components such as the transmission and rear axle.  Get a driveshaft loop.

Count your self as lucky there has been other on here that were not so lucky.

So Bart here bought a Chevy, tuned it, pushed it to its limits, proceeded to break it, and is now blaming Chevy? 

Wow. My head hurts.

Good luck with the warranty repairs.

Yep, bought a Chevy! Pushed it 12 mph past the 98 mph limiter, at partial throttle. Bad vibration started at 99 mph. By 110 it was very bad. Slowed down immediately. A few miles later of easy driving the rear seal in the tranny let go. I limped it 1/2 mile home. Had it towed to dealer next morning. Problem? Wait for it.......a defective bushing from the factory!!!! It would have done what it did in a few more miles anyway. It and the tranny are being repaired under warranty, as it should for defective materials and workmanship. In other words someone at GM screwed up! So all you guys blaming me can.....well you know! I will treat my Chevy as fragile glass from here on out cause that’s what you guys apparently do. All those payments we make for a sissy truck with no balls!!!! I bid you good day and happy holidays!! P.S. I do love the split seat heat and cooling, they feel great on my back. I’ll leave the manly work to my Ford though, it takes whatever I throw at it and comes back for more!!!!!

12mph beyond its designed parameters...that's like stating I only reved it to 9500rpm, I don't know why the engine scattered?"

Point is, they likely don't know what you did to it and simply said it was a bad part...

I realize you are an engineer. I’m a consumer and have driven all makes and models, owning over 60 vehicles in my lifetime. I’ve meticulously maintained all of them and without doubt have exceeded “parameters” hundreds if not thousands of times with out 1 single failure. No blown engines, no blown transmissions, no issues other than wear and tear. I demanded my military vehicles, of which I was signed for up to $200 million dollars worth also be meticulous maintained . None failed due to abuse. Unfortunately, wear and tear will always cause failures. The bottom line here is my Chevy was manufactured with a defect that would have soon failed at any speed. It’s failures were not linked to any parameter. It was linked to tolerances in machining.  That truck and every other should be able to withstand high speed wide open throttle for reasonable periods of time. Police vehicles are designed to run flat out without overheating till their fuel tanks run dry. Their civilian counterparts are designed to do the same but lack the extra cooling capacity to sustain such operations for more than just a few miles. I travel long distances and yes I do speed 90% of the time by at least 10% over the limit. I will continue to operate this way most likely for the rest of my days. I currently have approximately 3 million miles under my belt with this being the only driveline failure. Enough said! Happy Holidays.

Again, you cheated the system and got away with it...period.

Examples like this are why I get my completely stock and unmodified truck scutinized by the dealer at every minor warranty issue...because someone else cheated the system, and we are all assumed guilty from association.

Have a nice day...

Son you don't understand the nature of 'critical speeds' in harmonics. 2 seconds at the right sympathetic frequency is forever to the parts. In my oil/gas life I ran 180,000 hp. steam turbines I've seen them fail in les than 2 seconds from a ham handed operator thinking just as you are. It certainly is abusive and dangerous. Every spin out in 12 quarts of ATF at 110 mph? I've done it at 55 and it wasn't fun...for anyone...including those who were following and loved the effect of greased glass to drive on.

 

 The initial noise I heard was not descernable as a problem and occurred 4 days before the failure.

 

It happens and its sucks and it was the onset non the less.  

A few years ago I worked at an environmental testing lab, doing temperature/vibration testing on stuff for the gov't.  The vibe programs were very tightly controlled by computers, and in the rare cases when something went wrong and a resonanant frequency occurred, a second or two was all it took to destroy hundreds of thousands of dollars (or more) worth of really tough stuff that was designed for much greater stress environments than street trucks.

I’ve been around long enough to been in and driven some pretty wild trucks. I own a 92 that’s modified with original driveshaft. Can’t say how many times it’s been over 100MPH easy to do in Texas and west safely. Pretty sad in my opinion that these (modern) trucks can’t. I don’t drag race or go very fast like I use to, I like to be able to if needed. One of the reasons I don’t drive a new truck anymore.

Sounds like they've upgraded the driveshafts at least.  Didn't they use to blow up over 105mph or so?

You are missing the point not us.  YOU defeated the speed limiter and caused damage to your truck.  Not GM.

It is very doubtful that the speed limiter had anything to do with the truck having vibration issues. As it wound up, after the dealership installed a new torque converter, rebuilt the transmission, replaced the tail shaft housing, bushing, and oil seal, and replaced the front yoke on the driveshaft, the truck still had a vibration within the factory limited speed. The PICO machine was attached to the vehicle and after a drive down the interstate it was determined that the drive shaft was out of spec. The drive shaft was replaced. Unfortunately the truck still has a vibration, although slightly less pronounced, it now vibrates from 60 mph all the way to the speed limited speed of 97 mph. I suspect the rear axle assembly. The truck must have suffered some trauma during shipment? The odds of 75% of the drive train on a brand new truck with less than 650 miles on the odometer being defective is astronomical. The truck definitely is not up to GM standards and it is too bad because Chevy makes a beautiful truck and is the only manufacturer to offer split heat heating to only the back of the driver’s seat. Something I need for a disability, and the only reason I traded in my 2016 Toyota 4 Runner AWD Limited. For the time being I have parked the truck, not titled it, and am awaiting instructions from GM and/or my dealer as to whether they want the truck back, will assist me in trading it back in, or some other solution. I have $20,000 in equity tied up in this truck so it is very important that I get a serviceable and dependable truck capable of traveling long distances reliably. My dealership and their service department have been top notch and very professional. I intend to continue my affiliation with them regardless of the disposition of this truck. A vehicle is an assemblage of parts by humans. This vehicle just had several bad parts all come together in its assembly. I trust that GM will make it right. Time will tell.
